Probook 4710s, black screen, no activity: BIOS corrupted?

Hi, I have a HP Probook 4710s ENERGY STAR model. It is no longer the boot: the screen remains black, no prompt appears. The fan and hard drive run but there is no activity on the HD (LED this is not the signals). I think that has corrupted the BIOS. So, I tried to reload the original BIOS from a USB flash drive (512 MB), starting the notebook and holding the keys "Windows" and "B" with the power button (also tried with the combination "FN" + "B ", then simultaneously holding down the four arrows): I can see that in all cases the pendrive is found and read, but after a few seconds it emits only a constant flashing and nothing happens. During all these attempts, the LED on the "ALTBLOCK" flashes continuously at intervals of about 1 second.
Can anyone help me figure out what is the problem and how to solve it?
Also, I would like to know if this Probook uses a Phoenix BIOS, or if another type.
Thanks for the support
Flavio

M5400 - Black screen after updating BIOS

As the title says, I've got this unwanted black screen after updating BIOS with update utility from here http://support.lenovo.com/us/en/downloads/ds037429
What I've tried :
- power / battery out, pressing power button several times for short / long and longer time
- BIOS battery out for about half an hour
- wincrisis with USB bootable stick and BIOS extracted from BIOS update utility from support.lenovo
- different combinations of keys such as : FN + B / F / R +/- win key
What should I do next except finding a hammer ?

Hey,
I am having the same problem, I was updating my bios.. followed all directions which is necessary to update them.
And then when it was almost ready it said "Bios update is not responding" so I waited... and waited because I did not want to abort it but then Vista aborted it for me.
Well at first it did not seem to be a problem but then I noticed that I could not click anything (was still in windows @ that time did not reboot yet) then I wanted to reboot but nothing worked.. Pressing off button for a time to shut down did not work.. So eventually power was out. And it shut down.
So I hooked it up again but nothing happened. Pressing the "on" button made it start.. The DVD-drive loaded for a second but... that is it just a black screen :S
Going to bring it back to the shop tomorrow.

Hp pro tablet 610 G1 black screen after updating bios

After upgrading to windows 10, I updated bios recommended by hp official page for hp pro tablet 610 G1, but my tablet now turn into black screen and I could not do anything. Please help!!!
Any combination keys for this tablet to enter into bios recovery?

Quote from: flobelix on 23-August-14, 22:52:29
Ok, first of all update bios to the latest version which is 1.5 already.
>>Use the MSI HQ Forum USB flasher<<
A.) Download the attached archive and place it on your desktop. Do not decompress.
B.) Download and install the Forum flash tool.
C.) Insert your FAT32 formatted usb stick.
D.) Make sure that all win 8 options are disabled. (Fast Boot etc) Also make sure the legacy USB is enabled.
E.) Start the forum flash tool and select option 1. Then point the tool at the compressed archive we downloaded earlier. Then to your USB Flash Drive.
F.) Boot to the USB
G.) Now follow the directions and let the tool flash
H.) After flashing reinstall ME drivers in Windows: http://download.msi.com/dvr_exe/intel_me10_mb.zip

Qosmio F50-125 starts with black screen after an BIOS update

Hi
after instalation if new bios (v 2.0), computer sometimes starts with the black screen .
Even the first page that show press f2 to enter the bios is not shown.
Do you have somebody old version of the bios?
So I could try if it is the fault of it.

Hi
I think the old BIOS will not help you because the notebook would known that you are trying to update the BIOS to the older version and it would break up the procedure.
Furthermore the older BIOS is no available on the Toshiba European driver page.
I think just only a Toshiba ASP has got an older BIOS version.
Anyway, you said this happens sometimes.
This would mean that this issue doesnt persist always
Hmm. in such case I recommend settings the BIOS to the default settings and to update the display driver.
Check it out!

ProBook 4720s black screen

I had my laptop connected to external monitor via VGA, when I ran out of power and laptop shut down. After turning it on again, only my external monitor was displaying image, while the laptop's screen is completely black (not lit). When I booted to my Linux system, it recognized only my external monitor in the display settings, while Windows greeted me with a BSOD (not occurring in safe mode). I was booted into Arch Linux 64b with KDE when the laptop shut down. Could it be a software issue or a hardware problem? Please help, thanks.

Hello @trulex,
To get your issue more exposure I would suggest posting it in the commercial forums since the HP ProBook 4720s Notebook PC is a commercial product. You can do this at Notebook - HP ProBook, EliteBook, Compaq, Slate/Tablet PC, Armada, LTE.
The support page for your product may be helpful in the meantime:

Satellite L40-14H - Black screen after updating BIOS

Hello!
I have Satellite L40-14H (PSL48E) notebook. I have installed WindowsXP, it worked ok, except the digital keyboard was turned on permanently so I couldn't type a couple of symbols. Than I decided to install special BIOS for WinXP, that have downloaded from Toshiba web-site. The PSL48x model is in support list. Alter flashing from Windows and rebooting, I entered to BIOS to see what changed. I've seen nothing new, so I exit the BOIS and reboot again.
Since that moment, the notebook turns on, but the screen doesn't, it is black :-(((
Please help me, how can I back it to live?
Thanks, Eugene.

Hi, i have exactly the same problem. I have tried everything but with no success. Am really getting annoyed with this as the computer is only 10 months old and i can see that there are several people on these forums who have similar problems. Dont mean to sound negative but it dosent make me want to choose a Toshiba again in the future. Will try the customer support tomorrow but not really expecting much.

T60p - Black screen after success bios update

Hello!
I have a big problem:
Today I update my T60p bios to the latest, downloaded from the support site, via the windows based factory utility as usual (I do it more than 4 times before). Everything seems OK, but after restart the notebbok won't start. The sysfan is spinning, the leds are lights, but the screen is black, and no reaction for any keypress.
How can I fix this problem?
Thank's for help,
Peter

Hello,
first you could take out your battery and press powerbutton 10 times.
Insert your battery again and try to start.
If your cd drive is running, I would suggest to download bios as an iso-file and burn it to disk.
Then try to boot with this cd and flash bios again.
If these methods don´t work, than you´ll have to send it to service.
Good luck!

Blank screen after startup. bios corrupted

Hello,
I could really use some help I have a massive project due in a week and cannot access MATLAB anywhere but my laptop. Today windows decided to do its own thing like always and update itself which never seems to work right. But when restarting HP's terrible software also decided to attempt to update my bios. Like usual it failed and proceeded to corrupt my bios for the second time. Unfortunately this time I am out of warranty so they will no longer assist me even though this has been a recurring problem. Could anyone help me figure out how to get this working again? I have been searching Google, but nothing has worked for me I have an ho envy 15" which I believe model jt-1500. I really don't have anymore time to spend on scouring the internet with work and school and really need my laptop to just work again. I can also tell you I'll never buy an HP laptop again unless they can get their software figured out because I am afraid to ever update anything on my computer now.
Thanks for the help in advance

Hi,
As I dont have the computer infront of my I am limited in things I can do to fix the problem please try the following two things below to see if they fix your problem if they dont your only option will be take your laptop in for repair howerver you dont have to take to HP you can take it anywhere.
First thing I would like you to try is a power drain to do this remove the AC adapter from your pc and remove the battery, once you have done this press and hold the power button for 20 seconds once this is complete reinsert battery and AC adapter and try the computer again.
The next thing you could attempt is updating the bios this hopefully will install successfully this time, to do this press and hold down the windows key and the letter b on the keyboard then power on the computer still holding down the two keys it will attempt to update the bios.
Hope this helps,
James

Re: Satellite L40 - Black screen after updating BIOS

Hi everyone,
I have exactly the same problem as reported here:
http://forums.computers.toshiba-euro...threadID=35156
My portable is a Satellite L40-150 (Model PSL48E) It came with Vista and BIOS version 1.60
I updated the BIOS to version 5.50, because I wanted to install Windows XP. The BIOS update process went fine and the computer automatically restarted. Upon restarting, I entered the BIOS (pressing F2 key). I pressed F9 to load default settings and exited the BIOS, saving the changes.
The laptop restarted and the screen is now completely blank. Nothing appears in it.
I tried removing and then reinserting the RAM modules, but it didn't help.
So, I guess the only option is to return the laptop to a service center?
Why is Toshiba doing this? Are they doing this on purpose or what?
Regards.

I meant why is Toshiba releasing a BIOS upgrade that can render your laptop useless? (I've tried all the recovery methods they mention on their web, including turning on the laptop while pressing F12, but none of them work)
I've routinely upgraded the BIOS on all the computers I've owned through the years, and I've always reset the BIOS to its default settings right after upgrading. It's a procedure recommended by all manufacturers.
They all recommend to restore BIOS defaults after an upgrade because sometimes there can be some "leftover" configuration remaining from the previous BIOS version.
I upgraded the BIOS prior to installing Windows XP because it's the logical thing to do. Toshiba offers two different BIOS versions for my laptop, and the clearly state that one of them is compatible ONLY with Windows Vista, and the other one is compatible ONLY with Windows XP.
Could you tell me why should I install Windows XP on a laptop that has a BIOS designed for Vista? Common sense dictates that you should first upgrade the BIOS, and then install Windows XP.
I've contacted Toshiba's technical support and they will replace the laptop free of charge, because it's still under warranty.
I admit I'm satisfied with their customer care services, but I'm surely disappointed by their Quality Control. It has failed miserably in this BIOS release.
Regards.

Toshiba Satellite L755-S5216 Black Screen after failed bios update

There was a Toshiba BIOS update that went awry and now the computer won't turn on. I can hear the fans and see the lights, but all there is is a blank screen.

I'm not a tech support agent, but there are a couple things I would suggest doing.
While the laptop is off and unplugged, remove the battery, hold the power button for 10 seconds, restore the battery, and try the laptop again. If that doesn't work, try booting on only AC power without a battery.
If you still don't have any luck, give support a call at (800) 457-7777.
Good luck!

[SOLVED] UEFI with gummiboot: somtimes (!) just black screen

Hi,
since two days I'm trying to get UEFI work on my Lenovo T420. The problem is that there's only a black screen when activating the "Arch Linux" entry in gummiboot if I have not plugged in the installation medium (as a USB drive). If it's inserted sytemd starts booting but stops at a certain point complaining there are starting jobs running on /dev/sdc (the USB drive); then I get to the rescue shell. If it's not inserted there's just a black screen. To start the system I have to leave the USB drive plugged in and fastly remove it when systemd starts booting after selecting "Arch Linux" in gummiboot. I don't know why, but the system does boot then.
This is what I have done:
In BIOS I changed the settings that it's booting with UEFI "and" BIOS at least trying first BIOS and then UEFI. I followed the installation instructions of the Beginner's Guide (https://wiki.archlinux.org/index.php/Beginners%27_Guide) installing a system with LVM (ensuring that the install medium is booted in UEFI). I followed the recommendations of https://bbs.archlinux.org/viewtopic.php … 3#p1240883 concerning partitioning. This is the setup I have:
niklaas@len-t420-arch ~ % lsblk --output +UUID

(/dev/sda is Windows 7)
Please note that I /dev/sdb1 is the EFI System Partition and there's also another partition (/dev/sdb2) I created just in case I want to use a separate /boot partition. (Currently there's syslinux on it because I was experimenting whether I get the system to boot normaly, which means without the USB drive, by using Legacy BIOS and syslinux. But I was not successful: Screen also stays black.) This is what /boot looks like and the contents of /boot/loader/entries/arch.conf and /boot/loader/loader.conf:

niklaas@len-t420-arch ~ % cat /boot/loader/loader.conf
timeout 3
default arch
Additionally to the strange USB-drive-needs-to-be-plugged-in issue there is another one: Because there's a Windows 7 installation (unfortunately I need it) on /dev/sda with Truecrypt I decided to install two bootloaders: one is on /dev/sda and the other one on /dev/sdb. So I can "manually" switch between operating systems by using the boot manager that is provided by the BIOS of the motherboard which makes it possible to change boot priority quite simply. After the installation of gummiboot there was (of course) another entry created, so there are three:
1. Linux Boot Manager
2. ~first SSD (with Windows; /dev/sda)
3. ~second SSD (with Arch Linux; /dev/sdb)
When I select the first entry, even the USB-drive-trick does not work. There just resides the black screen. This I do not understand at all because, as already described above:
If I select the third option, gummiboot gets loaded and I can select "Arch Linux". Then, as already mentioned, there are three options: (a) USB-drive is inserted > I plug it off immediately after systemd starts > system boots (b) USB-drive is inserted > I don't (!) plug it off > systemd complains about starting job running on /dev/sdc > I get the rescue shell (c) USB-drive is not (!) inserted > I just get a black screen.
I hope the issue I have is quite understandable. Otherwise, please ask and I'll try my best to clarify things. Any help is really appreciated,
Niklaas

OK. I decided to use syslinux and installed it from the AUR. After installation was successfull, I copied all files as described in https://wiki.archlinux.org/index.php/UE … LINUX_6.xx to /boot/syslinux and ran command
# efibootmgr -c -d /dev/sdb -p 1 -l /EFI/syslinux/syslinux.efi -L "syslinux"
to create an entry. And I could just successfully boot without USB-drive. Thank you.

I guess, I also tried this before having the same outcome.
But I still do not understand what's happening when I select my second SSD; because there's still gummiboot loaded and I can still boot the system with the USB-drive. Does anybody know what's happening there? I'm totally clueless why the system is somehow accessing the flash drive?!

HP Envy X2 Black Screen on Boot

How do I boot from a USB? The device boots into a black screen. The BIOS works. I need to boot from a USB to initiate Windows recovery. Please help me.

Hello @nelsx ,
Welcome to the HP Forums!
I understand you have information about booting to USB on your ENVY x2.
You should be able to perform a recovery with the built in recovery partition by tapping F11 while the notebook turns on.
Otherwise, you may need to enable legacy mode in the BIOS and configure your boot order to allow USB boot. The following guide may help: Creating and Using a Microsoft Recovery USB Drive (Windows 8).
